If an user sends host notification without host status:
openstack notification create COMPUTE_HOST <host> <date> '{"event": "STOPPED"}'
logging registers silly error like object None has not method 'upper' and
notification gets status 'running', host is set in maintenance status.
It's impossible to set manually host status to non-maintanence
until there are host-related running notifications.
Running notifications are expired in 24 hours by default.
The patch makes engine to set 'ignore' status for such
notifications.

Masakari
Virtual Machine High Availability (VMHA) service for OpenStack
Masakari provides Virtual Machine High Availability (VMHA) service for OpenStack clouds by automatically recovering the KVM-based Virtual Machine(VM)s from failure events such as VM process down, provisioning process down, and nova-compute host failure. It also provides API service for manage and control the automated rescue mechanism.
NOTE: Use masakari only if instance path is configured on shared storage system i.e, 'instances_path' config option of nova has a path of shared directory otherwise instance data will be lost after the evacuation of instance from failed host if, * instance is booted from image * flavor using ephemeral disks is used
